The quickstart seems to get kubernetes-client dependency from kubernetes-maven-plugin. We upgrade to 6.x version which dropped customResource(context) DSL method. We need to use genericKubernetesResources() DSL method instead

[rohanKanojia]

Gradle equivalent quickstart doesn't seem to be affected by this since it's explicitly importing kubernetes-client dependency:

However, we should think about updating in there as well (maybe in a separate issue)
